Exchange between the stagnant and flowing zone in gas-flowing solids-fixed bed contactors / Razmena čestica između pokretne i nepokretne zone u kontaktorima gas-pokretna čvrsta faza-pakovan sloj
(Serbian Chemical Society, Belgrade, 2005)
In countercurrent gas - flowing solids - fixed bed contactors, a fraction of the flowing solids is in motion (dynamic holdup), while the other fraction is resting on the fixed bed elements. In this study it was experimentally ...
Study of gold-platinum and platinum-gold surface modification and its influence on hydrogen evolution and oxygen reduction / Površinska modifikacija platine zlatom i zlata platinom i njen uticaj na reakcije izdvajanja vodonika i redukcije kiseonika
(Serbian Chemical Society, Belgrade, 2005)
Surface modification of the electrodes was conducted from sulfuric acid solutions containing the corresponding metal-chloride complexes using cyclic voltammeter. Comparing the charges of the hydrogen underpotential deposition ...
Investigations of the reactivity of pyridine carboxylic acids with diazodiphenylmethane in protic and aprotic solvents, Part I: Pyridine mono-carboxylic acids / Ispitivanje reaktivnosti piridin-monokarbonskih kiselina u reakciji sa diazodifenilmetanom u protičnim i aprotičnim rastvaračima. Deo I
(Serbian Chemical Society, Belgrade, 2005)
Rate constants for the reaction of diazodiphenylmethane with isomeric pyridine carboxylic acids were determined in chosen protic and aprotic solvents at 30 °C, using the well known UV spectrophotometric method. The values ...
Mass transfer between a fluid and an immersed object in liquid-solid packed and fluidized beds / Prenos mase fluid-uronjeni objekat u pakovanim i fluidizovanim slojevima tečnost-čestice
(Serbian Chemical Society, Belgrade, 2005)
The mass transfer coefficient between fluid and an immersed sphere in liquid packed and fluidized beds of inert spherical particles have been studied experimentally using a column 40 mm in diameter. The mass transfer data ...
AFM studies of DNA structures extracted from adriamycin treated and non-treated Ehrlich tumor cells
(Srpsko hemijsko društvo, Beograd, 2005)
Atomic force microscopy (AFM), a unique tool to investigate drug treatment of cancer cells, was used to analyze the anti-neoplastic activity of adriamycin by comparing DNA structures of non-treated and adriamycin-treated ...
Vapour-liquid equilibrium of the OPLS, optimized potentials for liquid simulations, model for binary systems of alkanes and alkanes + alcohols / Ravnoteža para-tečnost OPLS, optimizovanje potencijala za tečnu simulaciju, modela binarnih sistema alkana i alkana + alkohola
(Serbian Chemical Society, Belgrade, 2005)
The NpT - Gibbs ensemble Monte Carlo computer simulation method was applied to predict the vapour-liquid equilibrium (VLE) behavior of the binary systems ethane + pentane at 277.55 K and 310.95 K, ethane + hexane at 298.15 ...
Synthesis of thermoplastic poly(ester-siloxane)s in the melt and in solution / Sinteza termoplastičnih poli(estar-siloksana) u rastopu i rastvoru
(Serbian Chemical Society, 2005)
Two series of thermoplastic elastomers, based on poly(dimethylsiloxane) PDMS, as the soft segment and poly(butylene terephthalate), PBT, as the hard segment, were synthesized by catalyzed transesterification, from dimethyl ...
The surface energy of disperse cadmium electrodeposits formations / Површинска енергија електрохемијског формирања дисперзног талога кадмијума
(Serbian Chemical Society, 2005)
The surface energy of disperse cadmium electrodeposits formation was determined by using a procedure described earlier.1,2 It was shown that the surface energy strongly depends on the composition of the solution from which ...
